Official forecasts from the Hong Kong Observatory indicate sunny periods and very hot conditions on August 28, with a projected range of 28–33°C under westerly to southwesterly flow. This setup stems from subsidence associated with Tropical Cyclone Saola, promoting clearer skies and higher insolation during the day while isolated showers and thunderstorms develop later. Ensemble models show modest spread, with some projecting afternoon peaks near 30–31°C due to lingering cloud cover and others reaching 33°C if breaks in convection allow stronger surface heating. The close market pricing around 31–33°C reflects this uncertainty in exact timing of any rain and boundary-layer mixing, with official guidance providing the primary upward bias for the higher end of the distribution.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 28 Aug '26.
The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm
This market can not resolve until data for this date has been published.
The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is initially published for this market's timeframe will not be considered for this market's resolution.Official forecasts from the Hong Kong Observatory indicate sunny periods and very hot conditions on August 28, with a projected range of 28–33°C under westerly to southwesterly flow.
